On Contested Ground: The Changing Nature of the Prairie Forest Ecotone
Saturday, September 19, 2:00–4:00pm
When the first Europeans arrived at the southern end of Lake Michigan in the 1670s, they encountered a rich and diverse landscape largely carved by the last great glacial incursion. Grasslands dominated the flat areas that burned regularly, with transitional savannas and shrublands thriving where the flames appeared less frequently. In ravines and along the eastern shores of rivers, where the burning was infrequent, forests reined. Interspersed were varying kinds and sizes of lakes and wetlands, from Lake Michigan to the Kankakee Swamp encompassing up to a million acres. This was a great ecotone where the prairies competed with forests.
Joel Greenberg, author of A Natural History of the Chicago Region and Of Prairie, Woods, and Water, takes a look at how this area has changed over the course of the last 300 years. Much has been lost, some has been saved, and there is much that can be done to ensure that future generations will be able to enjoy the natural beauty that remains. $25 (Members $20) Register by September 17
Greenberg’s books will be available for purchase and he will sign books following the lecture.
